Don't do this manually, Dylan will work on doing it automatically
tomorrow as part of fixing the hash identifier. Getting our posting
numbers back up to par is more important than the hashes right now.

That could work. I would say use the "old skool decoy" setting in the
interface. The longest part would be choosing the project for each
torrent file.

        Those torrents are still stored on the Torrent FTP server. Could
we possibly just re-add those torrents/hashes back into the database.
It may take a while but I imagine it is still is possible.

        All-

         

        In an attempt to copy the data that the torrent team entered
into the old database, I managed to wipe out the last 6 days of data.
Go me! So, this means that now everything from 5/23 to 5/30 is going to
say that it's real no mater what you use, since there aren't entries in
the database for it.

         

        Anything that is being tested should be checked for mod 137 to
determine if it is ours or not for the next few weeks if the identifiers
say it's real. (The mod 137 check, of course, doesn't need to be done
if it returns that it is ours.) There is no way around this, since
there is no way to get the data back.

         

        I'm also going to make a change to the hash identifier/torrent
interface that will screen out the garbage that some sites add to the
torrent file (which was causing false negatives). Expect the new
versions tomorrow. For now, just use the torrent interface (and stop
using the hash identifier already).

         

        -D

                Q: Dan asked what caused case 1.

                A: Some data was entered into the old database by Rendy
and Gerald (they must have been using the old version of the interface).
I am going to do another dump from the old database to the new database
for several tables (should only take a couple hours.) Will email when
the dump is finished.

                        Oh ok, we can wait for the new version...

                        But these errors are caused by the torrent
interface that's supposed to point to the correct DB. We're not just
seeing errors with the QA hash identifier.

                        T-

                         

                        I sent an email last week to Dan that, I think,
was CCed to the QA team saying not to use QA's torrent hash identifier
until I had a chance to update it. The work around was to get the
torrent interface, since that is pointing to the correct database.

                         

                        I will make a new version of the hash identifier
today and email QA team when it is ready.

                                Dylan,

                                 

                                The hash identifier is reporting the
hashes incorrectly and reporting some errors. See below for details.

                                Here are the mislabeled hashes that I
found on the Universal Pictures 5-29-07 torrent results. Also currently
getting a "Database query error! (0x100B) bt_generator_maininfo" error
when trying to check hashes in the BT Interface.
